Q STEAM-DRIVEN COMBINED HEAISIN'G ANn :inREsHiNG MACHINE.

To all 'whom/it concern:

.Be it known that I, LEWIS K. BROWN, a

citizen of the United States, residing at` Asotin, in the county ofAsotin and vState of lWashington, have invented new and usefulImprovements in Steam-Driven Combined Heading and Threshing Machines, of

-whicli thefollowing is a specification.

This invention relates to a steam driven combined harvesting andthreshing? machine embodying in its general organization a rea ingdevice and a threshing, separating an cleaning mechanism to-which `thema` terial cut by the reaper is delivered by suitable conveyers whichare continuously driven during operation of the machine together withpower engines carried on the machine 'for propelling the latter from theground and for driving the reaping, conveying, threshing, separating andcleaning mechanisms.

The invention has for its objects to provide a comparatively simple,inexpensive machine of'this type whereby the grain will be harvestedduring forward travel of the machine over the ground and delivered ontothe conveyers, one wherein the latter will be properly and continuouslydriven. for carrying the grain to the threshin mechanism, one innwhichthe operation o .the various `mechanisms may be controlled at will andthis irrespective of the machine being at rest or in motion over theground, and one which will travel in its own swath throughs. fieldwithout treading down any .of the-standing gram.

AV further 'object of the invention is tof provide an improvedlight-weight portable mechanism for -separating the grain from thestraw, and to. reclean the grain after it passes the ordinary sh'oe andbefore it passes from the machine.l I

A further object .of the invention is to provide a siinplifiedpropellingmechanism for driving the machine in its travel over the ground,together with means for steering the machine and yieldably supporting`the framework of the latter which inl turn sustains Athe enginesand-attendant parts.

l/Vith these and other objects in view, the invention comprises thcnovel features` of construction and combination of parts more,

.fully hereinafter described.

In the accompanying drawings: Figurer is a side elevation of aharvesting and threshing machine embodying the invention.

Fig.1li is aplan view on an enlarged scale of a portion of the sickle blade,together with lits operating lever. Fig, 15 is a` detail `view,- pai'tlyin yvertical cross section and on an enlarged scale, of the sickle barand its -attendant parts. Fig. 16 is a detail front ele-A vation'of thesickle blade as viewed in the direction 'of the arrow in Fig. 15, andshows the sickle drive in detail. i

Referring'to the drawings,'it will be seen vthat the machine, the frameof which includes a horizontal table 1, is mounted for transportation on a Vrunning gear comprising a rear axle 2- equipped with transportingwheels 3 and a front axle 4 having pivoted end portions or sections Gadapted to swing on a horizontal plane and on which are keyed the fronttransporting wheelsv 5, having hubs set out, bringing the wheell'ieaings under the boxings 7 or sleeves, Fig. 7. These sleeves haveupwardly and downwardly extending arms 'Ta terminating in pivots 7 thatturn in bearingsi'c on the housing 61, which Alatter .carries the weightof the front end of the platform 1. To the sleeves, which swing uniformmovement by a link 9, and pivoted von vertical axes by the pivots 7b,are fixed linwardly and rearwardly projecting arms 'having their forwardends connected for y to one of the arms is a rack bar 10, the teeth 11of which are in mesh with a pinion 12 in turn fixed at the lower end ofa vertical steering post 13. This post rotates in a bearing 121 on thehousing 61 and has fixed on its Vupper end a hand wheel 14 through theme-A reaper frame 17 adapted to swing in a verti cal plane toward andfrom the ground surface and to be normally supported in elevatedcondition through the supporting members or beams 18 pivoted to theplatform and provided at their forward ends with shoes or runners 19which travel on the ground surface, there being fixed to the bars 18vertically uprising standards 20 which proj ect upward through theguides 21 on the back of the frame 17. The upper ends ofthe standardsare toothed to form racks a and are connected together by means of ashaft b sustained at the top of the rear portion of the platform 17,there being fixed on the ends of the shaft pinions c, meshing with theracks a and serving to maintain 'the outer ends of the frame 17 at equaldistances from the ground, while the height of the sickle on thebalanced platform 17 is regulated by means of a bevel gear d fixed onthe shaft b and engaged by a bevel pinion e carried by a shaft farranged counter to the shaft I) and extended rearward to the operatorsplatform and provided at its rear end Witha crank wheel g adapting theparts for convenient operation.

Journaled in bearings 22 in the frame 17 is a rotary reel shaft 23carrying a rotary feeding reel 24 which in practice directs the grain orother material to be cut inward between the fingers of a stationarysickle bar 25 sustained at the front of the reaper frame and coperatingwith a reciprocatory sickle blade 26 for reaping the grain in the usualmanner, while pivoted intermediate its ends between a pair of verticalbearing standards 27 is a balance beam 28 provided at its rear end witha weight 29 and having its forward I end connected by a link 30 with therear side of the reaper frame 17 for balancing the latter.

Extending longitudinally of the frame 17 is a pair of endless conveyorbelts 31, 32, of

which the former travels upon rollers 33 andv 34 journaled in the frame,while the belt 32 is arranged for travel on rollers 35 and 36, the belts31 and 32, which are spaced apart at their inner ends, being soconnected for operation that their top portions travel toward oneanother, while sustained at one side of the platform 1 and extendinglongitudinally thereof is a rearwardly and upward ly inclined conveyerbelt 38 having its forward end positioned in the space between the innerends of the belts 31, 32, for receiving material therefrom, the rear endof the belt 38, which is arranged for travel over rollers 39 and 40,being disposed for delivering material through the opening 41 into thecasing 42 of a threshing mechanism sustainedat the rear of theplatform 1. The portion of the forward end of the belt 38 .which liesbetween the ends of belts 31 and 32 is held for travel in a horizontalplane by means of idler rollers 43, as seen more clearly in Figs. 12 and13.

vArranged beneath the platform 1 is a Water tank 44 designed to render,the platform more rigid and to carry water for feeding a boiler 45sustained on the platform and in turn connected by means o f a pipe 46with an engine 47 and by a steam pipe 48 with a pair of' engines 49,,both of which are connected for driving a main power shaft 50 on `whichis fixed a pinion 51 in mesh with a gear 52 fixed upon a second drivingshaft 53' arranged vertically beneathy and for operation from the shaft50 on which there is also fixed a fly wheel 54, while fixed on the shaft53 is a sprocket pinion 55, connected by a chain 56 with a sprocket gear57 arrangedv on the front axle 4 for driving 'the latter, there beingalso fixed on the shaft 53 a. sprocket pinion 58 connected by a chain 59with a sprocket gear 60 on the rear axle 2 forndriving the same. It isto be observed in -this connection that the gear 57 on the frontaxle ishoused in a metal casing 61 which carries the front end of the platform1 on its gudgeons 61 and that the rear axle 2 extends through a tubularcasing 62 extended transversely through the tank 44 and serving torelieve said axle from contact with the water in the tank, and to forman adequate space in which the shaft operates, while at the forward endof the tank is formed a housing for the counter shaft 53 anditsattendant gearing and bearings, these parts being all fastenedtogether in one piece, thus rendering the platform rigid. It is to beobserved in this connection that the platform 1 extends at its forwardend over the housing 61 and that the tank '44 is y a sleeve 67 arrangedor rotation on the axle l 4 and independently' thereof, it beingunderpermitting'proper differential rotation of stoodthat thevaXle-isconnected for driving one'of the front wheels whiley the other ofsaid wheels turns with the sleeve, this arL rangement being for' thelusual purpose of the wheels inthe operations of turning and guiding themachine.

v Extended longitudinally of the reaper frame 17 and journaled insuitable bearings at the rear thereof is a shaft 68 geared by a chain69, 4arranged on suitable sprockets,4 with the reel shaft 23 forrotating thereel` and also connected by'a cross belt 70 with a shaft 71from which the conveyer 38 is driven by means of a chain belt 72 leadingto the shaft 7 3 of the roller 40, there being fixed on the shaft 71 abevel gear 74 in mesh with a pinion 7 5 fixed upon and for driving acountershaft 76 which is in turn connected by a chain belt 77 with ytheshaft of roller 36 Yfor driving Vthe conveyer-32. The' conyeyer 31 isdriven through the medium of a cross belt 76', Figs. 2 and 11, from apulley on 76 tocountershaft 76 above, thence by 'sprocket cha-in 77` toroller 34, while the shaft 71 is drivenby means of a chain belt 78 froma countershaft 79 in turn geared through the medium of a chain belt 80with the main drive `shaft 50. The belt 80 is arranged for travel upon asuitable sprocket wheel on the shaft 79 and a corresponding sprocket 81mounted idly on the shaft 50,

the last named sprocket being provided with a hub 82 having clutch teethin normal engagement with corresponding teeth formed hell crank lever,

.on the hub 83 of the fly wheel 54, as seen more clearly in Fig. 10,there being coiled upon the outer end of shaft 50 a compressible spring84 designed to act upon the sprocket 81 for maintaining the clutch teeththereon in engagement with the clutch teeth on the hub 83. It will beobserved in, this connection that during reverse rotation of the shaft50 in' the operation of backing the l machine the clutch member 83 mayturn independently ofthe sprocket 81, thereby automatically throwing thereaping mechanism and conve ers out ofaction K n The movab e sickleblade 26 is reciprocated through the medium of va bell crank lever 85fulcrumed atits elbow as at 86, and having one of its arms" engaged withthe blade and its other arm connected by means of a link 87 with aneccentric head`88 'fixed on the shaft 71 and having a wristpin 89engaged with the rear end ofthe rod 87 it being understood that as thershaft 71 re-i volves the pitman rod 87 will. `actuate the which in turnwill reciprocate the sickle blade. y

The :threshing mechanism, which ishoused in thercasing 42 includesathresher cylinder teeth 92 fixed in the perforated grain bed 93 above'which there is also arranged a plurality of beater cylinders or drums94.-

equi'pped with teeth 95 and adapted to act upon the grain after itpasses beyond the action of the thresher cylinder 90, the cylinders 94being connebted for rotation one from another through the medium of an'endless sprocket belt 96 arranged for travel around sprocket wheelsfixed on the ends of the cylinder shafts andA to be driven from theslaaft 97 of the engine-47 by means of a belt 98 arranged for travel ona belt wheel 99 fixed on the engine shaft and a belt pulley 100 fixed onthe shaft of one ofthe `cylinders while the thresher cylinder 90 isdriven from the shaft 97 through the medium -of a belt 101 arranged fortravel on a belty wheel 102 fixed on the shaft 97 andon a belt `pulley103 fixed on the shaftof cylinder 90, it being understood, of course,that while the engine is inthe operation of driving the'shaft 97, the`clined chute 104 while a rreversely inclinedl` chute 105 is alsoarranged beneath the bed under the beating rollers 94. The' .chutes 104-and 105 are connected for uniform move 'ment by means of a bell cranklever 106 and further sustained for oscillation in the casing by meansof links 107, the chutes being adapted to deliver the grain onto theupper end of a downwardly and rearwardly inclined screen 108 having afinely perforated forward portion 109 and acoarsely perforated rearportion 110 beneath which latter-there is disposed adownwardly andforwardly inclined pan 111 adapted to direct the material into anunderlying conveyer trough 112 containing a tailings conveyer screw 113,the material passing through the por-tion 109 of kthe screen being inlike manner directed to an underlying conveyer trough 114, containingV aconveyer screw 115, by means ofV asys- `tem of underlyinginclined pansand screens 116, 117, 118, and 119 and of which the pans 111, V116 and118 are composed of metal. If desired, there maybe arranged in thecasing 42 just above the delivery end of the con: veyer 38, abeater144'driven from the shaft 73 by a belt 144. r l Y Mounted on theouter face of the rear side wallv of the casing 42 and havingcommunication with the latter is 'a pair of conveyer ducts and 121, ofwhich the former communicates at its' lower end with the conveyer trough112 andelevates the tailings back to Y the threshing cylinder 90 throughthel mel dium of a spout 122, while the duct 121 com muiiicates at itslower end with the tiougli 114 which takes the clean 'grain to thesacker to be cared for.

Fixed on the shaft of the Central beater roller 04 is a pulley 131 towhich is ecceiitrically pivoted a pair of pitinen 1252 and 133, of whichthe pitnian 1232 is connected with a crank arin 1I32f in turn fixed on ashaft 132" carrying the triple crank 106, while the pitman 133 isconnected with a crank 133 crank 134 for osciliating screens 11T, 11S)and pan 118. rIhe conveyers 1125 and 115` and the elevators are drivenby convenient pulleys on the projecting shafts througii thebeatersv94,'while disposed for rotation iii the threslier casing 42 andto direct a blast of air onto the screens is a. fan 141 in turn inclosedwithin a fan casing 142 fand coniiected to be driven from the right handbeater roller. 94 through the medium of a crossed belt 143.

The platform 1, which carries the engines, boiler and attendant parts,is yieldably sustained at its forward end through the inediuin ofvertically coinpressible supporting springs 146, which by means ofinterposed boxing rest on the gudgeons 61 and at its rear end by meansof similar springs 147 which bear at their upper ends beneath members orrails 148 and at their lower ends upon bearing levers 149 in which therear axle 2 is journaled and which are in turn pivoted at their forwardends as lat 150 to the frame of the machine and mounted at their rearends upon vertical guide members or bolts 151, as'seen more clearly inFig. 6.

The device connecting t-lie bell crank S5 with the sickle is shownclearly in Figs. 14, 5 and 16. In Fig. 15 is shown how the plate portionof the bell crank S5 passes through the breast of the reaper platformand extends out under the sickle bar 152 and has the adjustable parts153 bolted thereon. Fig. 16 shows how the sickle bar 152 yhaving thecutting sections 26. attached may be in tw-o pieces abutting together asat 154, the two sections of the sickle bar being bolted between 155 and156 as shown, 155 having a boss onethe lower side which is engaged bythe adjustable pieces The pieces 153 are fastened to the plate S5 bymeans of cap screws 157 passing through slotted holes in 85" and screwedinto the pieces 153, and by the taper bolts 15S passing through slottedholes in the pieces 153 and the plate S5. vThe slotted holes are shownby the dotted `lines in Fig. 16. The 'pieces 153 engaging the boss on155 may be adjusted to take up all lost motion or looseness causing jarof the working parts by ytightening' the tapering bolts 15S.

i In practice, the engines having been setin motion, the machine willtravel over the ground and they reaping, conveying and .fixed on shaft133" carrying athreshing devices will bedriven through the medium of thevarious sets of gearing, as heretofore eXpla1ned. As the machineadvances, the sickle blade 26 will cut the grain or other material,which will fall onto the conveyers 31 and 32 from which it is receivedby the conveyei' 3S and delivered thereby into the casing 42 through theopening 41. After entering the casing the grain tirs-t passes under andis subjected to the action of the thiesher cylinder 90 and thereafter tothe action of the beater cylinders 94,

-whereby they grains will be effectually removed froin the slieaths, thestraw finally passing into the s tiaw receivingv chamber 152 at. therear end of the casing 42. The grain falls as usual through theperforated bed 93 onto the chutes .104 .and 105 and thence passes to theunderlying screens and pans. Upon falling onto the screen 108 the cleargrain passes through the. portion 109 of saidscreen onto the underlyingsystem of screens and pans by which it is finally delivered into thetrough 114 and carried therefrom by the screw 115 into the conveyer duct121 for final delivery into grainl sacks.

-The coarser particles of material falling onto the screen 108 pass ontothe portion 110 thereof through which it isdelivered to the underlyingpan 111 and directed by the lat ter into the trough 112 from which it isconveyed by the screw 113 into the duct 120, thence carried back to thecylinder 90 for rethreshing.

It `is to be noted that during forward movement of the machine theclutch mem.

bers 82 and 83 formed respectively on the Asprocket pinion 81 and wheel54 Will be maintained in engagement by the spring 84.but that when itbecomes necessary to back the machine i'n the operations of turning orthe like the spring 84 will be coinpressed, lthus permitting the teethof the clutch member 82 to ride idly over the teeth ofthe companionclutch member, `\whereby the mechanism for driving the harvesting vandconveying devices will be thrown out of action, it beingunderstood thatthe threshing mechanism is independently thrown out of action bystopping the engines 47.

It is to be understood that any engine or motor of sufficient power maybe placed ony the abovedescribed platform and connected to the machineryfor operating the same.

Having thus described the invention, what I claim is L 1. Thecombination of a wheelsupported frame, runners or ground-engagingmembers extending forwardly therefrom, a reaper frame extendingtransversely in front of the irst-mentioneiil frame,` upwardly-extendingmembers on the runners, rack bars on the members, guides .on the reaperframe for receiving the members, piiiions engaging the rack bars, andmeans for actuating the -pinl ions for I f from and supportedI on therunners and lomeans on the frame ,operating through the,
